IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 142,634, dated September 9, 1873; application filed February 1, 1873.

To all whom it may concern:

Be it known that I, PETER vKENDRICK, of Trenton, in the county of Mercer and State of New Jersey, `have invented a new and Improved Car-(Jouplin g, of which the following is a specification:

The -object of my invention is improvement on the car-coupling of Depeu and Hall, patented-July 2, 1867, and Smith and Utton, patented September 12, 1871; and the invention consists in employing a headed bolt sliding in opposite slots of the draw-head and a link with a cross-stud for strengthening it, as hereinafter described.

Figure 1 is a longitudinal sectional elevation of my improved car-coupling. Fig. 2 is a horizontal section. A

Similar letters ot' reference indicate corresponding parts.

A represents the draw-heads, which have a long chamber, B, behind the opening C in the en d for the link; also, a long slotted hole, D, for the pin E; and also another round hole, F, for a pin, G. H represents links with a crossstnd, I, in the middle to strengthen the ends, by preventing the sides from springing together, which allows the metal to stretch around the coupling-pins so as tobreak readily. The chambers B are about as much deeper than the bottom walls of the holes G as the thickness of the links, so that one `link lying in the chamber behind the opening G will allow another to be putin over it for coupling, as represented in Fig. 1.

It will be seen that, by having the pins E slide back in this way with the links, the latter are protected from injury by the draw-heads or other links striking against them. It will also be seen that, by having the links permanently secured by riveting or heading the pins E in the buffers, and by having a link on each buffer and using another coupling-pin, G, I secure the links against loss.

I may avoid the striking of the links on the end and the cross pieces by having a slot through one of the vertical walls of the opening of the end of the draw-head and swinging the link around out of the way of being struck but I do not consider it as good an arrangement as the one represented in the drawings.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The link H, provided with the central cross-stud I, in combination with the doubleheaded bolt E and draw-head, provided with opposite longitudinal slots D D, whereby the link and,bolt may be pushed back together into the `draw-head, as set forth.

2. The combination of the link H, havingv the cross-stud I, with the bolt E, pin Gr, and draw-head A, provided with the slots D and holes F, whereby said link may be sustained in a position for automatic coupling, when the pin G'isinserted in its proper place, as set forth.
